I'm using an AD9172-FMC-EBZ and have been able to successfully configure the DACs to run in wideband mode 11. I am not able to use the NCOs in the AD9172 for my application because I'm clocking an ADC with the same sample clock as the DAC and am using direct sampling. I would like to use the second Nyquist zone image, but due to the sinc-like power vs freq output, the power in the second Nyquist zone image is nulled out. I have used a "MIX MODE" feature on other DACs before that had an inverse-sinc filter on the DAC output to boost up the power in the second Nyquist zone image. I didn't see a feature like this in the AD9172, but figured I'd ask if it's possible, since I believe I've seen MIX MODE in previous generation ADI high-speed DACs.
Sorry, just saw this previous post on the same question. Hope there was a good reason for removing this feature!
You are right. Our previous DACs(i.e. AD9162 family) support mix mode. however, we changed the AD9172 architecture that doesn't have support mix mode.
Do you have specific RF range in 2nd NQZ you want to operate? We can take a look at if we can find a better Balun to boost the power of the 2nd NQ image.
